Game event recognition for user generated content

ABSTRACT

Automated detection of events in content can be performed using regions of information associated with various user interface or display elements. Certain elements can be indicative of a type of event, and regions associated with these elements can be analyzed on a per-frame basis. If one of these primary regions shows a state or transition that is indicative of one of these events, one or more secondary regions can be analyzed as well to attempt to verify whether that event occurred, as well as whether that event qualifies for selection for additional use. Selected events can be used for purposes such as to generate highlight montages, training videos, or user profiles. These events may be positioned at different layers of an event hierarchy, where child regions are only analyzed for frames where a parent region is indicative of a type of event.

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation application and claims priority to U.S. patent application Ser. No. 17/075,377, filed Oct. 20, 2020, entitled “GAME EVENT RECOGNITION FOR USER GENERATED CONTENT”, the full disclosure of which is hereby incorporated herein by reference in its entirety for all purposes.

BACKGROUND

Digital content available to end users is continually increasing in complexity and image quality. Content such as video games also comes with increasing types of gameplay available to players, as well as different types of experiences, such as video streaming for non-players and tournament access. Accordingly, approaches to analyzing such content have become more complicated as well, which can prove challenging for devices with limited capacity or where maximum latency requirements can come into play.

DETAILED DESCRIPTION

Approaches in accordance with various embodiments can identify various events or occurrences in media content. This content can include any appropriate type of media content, such as may include audio, video, or image content presented as part of a video, audio, video game, virtual reality (VR), augmented reality (AR), captured performance, or other such experience. In at least one embodiment, this media content can include audio and video representative of one of these other types of experiences, such as streaming video of a gaming session of another player. In at least one embodiment, the types of events or occurrences may depend at least in part upon the type of experience, such as for a gaming experience versus a VR experience. In at least one embodiment, the type of event may also depend on a specific instance of that type of event, such as a specific game being played for a gaming experience.

For example, FIG. 1A illustrates an image, or frame of video content, corresponding to gameplay of a particular user. In this example, the game is a first person shooter (FPS), or at least a game with an FPS mode, in which a player moves a virtual player through a virtual world to attempt to perform various tasks, which often involves the elimination of one or more enemies, characters, non-player characters (NPCs), or other players. There may be many events or occurrences during a session of such a game, as may involve a player killing an enemy, completing a level, collecting an item, or completing a puzzle. There may be a number of reasons one might want to identify these events, such as to generate player statistics, generate a highlight video, generate a training video, determine player skill level, and so on. In instances where this functionality is generated from within the game, or has at least some integration with a game engine or game server, this information can be provided from the game itself. In other instances, however, this information may not be available from the game and must be determined using only output of the game, such as audio, video, and/or control feedback provided by, or for, the game. In some instances, this may take the form of a gaming platform or video streaming service that may have access to audio and video content for gameplay. That platform or service may want to provide highlight videos, training videos, gaming montages, or other forms of content that are generated from video of game content. In order to accomplish such tasks, this platform, service, or other entity may need to be able to determine events or occurrences represented by that content that are noteworthy or potentially of interest to one or more end users.

One approach to determining events of interest is to analyze the individual frames of video content. In at least one embodiment, this can involve analyzing all content in an image to attempt to identify objects, occurrences, events, actions, or other things of interest that are represented in this content, which hereinafter will be referred to as events for simplicity, although such usage is not intended to limit to only events or limit the interpretation of an event to only these examples. This analysis may include, for example, analyzing the image, audio, and/or video content using one or more neural networks to attempt to recognize or infer any of these events. As illustrated in image 100 of FIG. 1 , however, there may be many different objects in an image that may change between frames, such that analyzing and tracking all this content over time may be too resource intensive or may come with too much latency for at least some applications.

In at least one embodiment, there may be certain regions of an image that correspond to specific types of information associated with one or more events of interest, such that the complexity of analysis can be reduced by limiting at least some of the analysis to these areas, and attempting to detect or identify certain states or changes in states (e.g., transitions) of content in those regions. For example, it might be desirable to know when a player eliminates another player for purposes of generating a highlight video or montage. Video or image data rendered for the game may include one or more user interface elements 102, 106 that indicate when a player in a game session is eliminated. There may be various other regions that correspond to graphical user interface (GUI) or heads-up display (HUD) information as well, which may be useful in identifying these and other types of events that occur during gameplay. For example, image 100 includes regions that correspond to various UI elements, as relate to time remaining 104, in-game chat messages 108, type of ammunition or weapon selected 110, amount of ammo remaining, shield 114, health 116, virtual player cash 118, and location 120. There may be other regions associated with information that only appears at certain times, such as when a player dies and is spectating gameplay of another player. The information contained in at least some of these regions can change over time, and those changes can be indicative of various types of events. In at least one embodiment, events can be determined by detecting changes in one or more of these regions, and combining information for that change with information in one or more other reasons that may be used to determine a type of event that has occurred. For example, if a user element 102 indicates that a player has been eliminated, a player's cash 118 goes up by an amount associated with a kill, an amount of player ammunition 112 went down, and a chat message 108 indicates that a current player killed that other player, then a determination can be made with high certainty that this player eliminated that other player, even if the actual elimination (e.g., the shot by the current player that killed the other player's avatar or character) was not detected or not analyzed in the video data. If an element appears in a region to show that a player is simply spectating at a specific time, then any kill that occurred at that time was not initiated by the player and then therefore may not qualify to be selected for a highlight, depending at least in part upon the relevant event rule or selection criteria. Various other actions or events can be determined as well, as may relate to a player skydiving, achieving a higher level, or performing another action or accomplishment that may be worthy of inclusion as a highlight.

In at least one embodiment, information in each of these regions can be analyzed and/or evaluated for each video frame in order to accurately detect game events. Such a brute force approach can be relatively resource intensive, however, particularly for a large number of events of complicated elements that may be contained in those regions. For example, in many cases a UI element will be overlaid on varying gameplay elements over time, and it may take some amount of segmentation or image recognition to determine those elements for different frames.

Approaches in accordance with various embodiments can take advantage of the fact that there may be specific regions that are highly indicative of the occurrence of an event, or that will change or have a specific state or value corresponding to an event of interest (although these elements may change for other events as well). For example, if player eliminations are to be used to select highlights for a video, then a UI element 102, 106 that updates each time a player is eliminated can be a primary indicator of the occurrence of this event. If a player elimination icon is not updated or does not undergo a change in state, then there is no reason to evaluate other information in the image to determine whether a current player eliminated another player.

It may be the case that highlights are not being generated for an entire game session, or all players therein, but may be generated for a specific player, and is to include only highlights that are relevant to that player. In such a situation, the changing of the player elimination UI element 102 may be insufficient to identify an event where a current player eliminated another player, as there might have been another reason for that other player being eliminated, such as by falling off a level or being killed by a different player. Accordingly, it may be necessary to evaluate information in these other regions as well. In at least one embodiment, events of interest may therefore have a primary region identified that is indicative of a type of event occurring, after which information in these other regions can be analyzed, such as may be part of a multi-pass process. In this way, many of these “subordinate” regions (or child regions in a region hierarchy) then are only analyzed if a state or value of an icon, text, or other UI element in a corresponding primary region has changed or otherwise had a specific state presented. In at least some embodiments, the subordinate regions that are evaluated for a specific type of event may include only those that are determined to be relevant to that type of event, as may be determined using one or more rules generated, customized, or otherwise provided or obtained for that type or instance of content. In at least one embodiment, these subordinate regions can also have parent-child relationships among them.

FIG. 1B illustrates another example image 150 corresponding to a frame of gameplay. As illustrated, this image contains various objects, as well as a number of UI elements. In at least one embodiment, at least some of these UI elements can be assigned to primary or subordinate regions that can be used to identify specific types of events or occurrences. In this example, the player is driving a vehicle in a racing game, or at least a racing mode in a game session that may include multiple different modes of gameplay. There may be multiple events of interest in such a game, such as a player winning a race, taking the lead, or wrecking another player. For each of these types of events, there may be a primary region identified that is indicative of that type of event. For example, this display includes regions for UI elements relating to time remaining 152, players eliminated 154, mode of operation 156, speed 158, engine load 160, location 162, leaderboard 164, position 166, and score 168. For each type of event, there may be a rule indicating which region is a primary region, and which regions are sub-regions. As will be discussed in more detail later herein, these rules can also specify subordinate regions of a region or event hierarchy, where those regions are only evaluated in response to a state, or change in state, of at least one region at a higher level in that hierarchy.

For an event where a player passes into first place, a primary region may be the place indicator 166 and/or the leaderboard 164. While a position region 166 may be enough to indicate that a player has entered first place, that may have resulted from other players dropping out of the race or the player being the only human player racing at the current time, which may be determinable in conjunction with the leaderboard 164 or player elimination icons 154. A map 162 can also be used to determine proximity of other vehicles, which can be used to determine whether an event is highlight worth, such as where there are other vehicles nearby, and preferably just behind a current player's vehicle. Thus, at least these regions may be evaluated to determine whether the player entering into first qualifies for a highlight by satisfying at least one highlight selection criterion. For example, a player passing the first place car may qualify, but the player entering first place because the other player drops out of the race may not qualify for highlight selection. As with the prior example, an elimination event may use an elimination icon 154 as a primary region, with other subordinate regions evaluated to determine whether a current player was responsible for that elimination (or whether that elimination otherwise satisfies a criterion for highlight inclusion). Winning a race may be determined using a primary region that indicates victory or place, but information in other regions such as other players still playing or having time left on a clock may be necessary to determine whether to include this event in a highlight. As will be discussed in more detail later herein, selection of an event for inclusion in a highlight video may include pulling at least some video before and after event detection from a buffer for inclusion in that highlight video. In other embodiments, a time stamp can be stored for that highlight, along with event information such as type of event, and that information can be used to extract relevant portions of that video at a later time for dynamic highlight video generation, such as where a viewer wants to see only a certain type of highlight, such as only kills, takings of the lead, or victories.

FIG. 2A illustrates a set of example regions 200 that can be identified for a given game, or mode of gameplay within a game. In at least one embodiment, these fields or regions can be selected or customized specifically for a game, game mode, or type of game. As mentioned, each of these fields or regions may correspond to a specific type of information located in a specific region, or locatable region, in an image or video frame of gameplay, where that information may be represented by text, an icon, or another graphical object or element. In at least one embodiment, at least one audio region may be specified as well, as may relate to a sound or music that plays in response to, or along with, a type of event. Other output, such as haptic feedback, may be analyzed if that information is available. In this example, each of these regions can be treated similarly, such that they can all be evaluated concurrently for each frame using a brute force method, or for at least a subset of frames in a video, such as every third frame if it is desirable to reduce resource requirements while still able to retain event detection accuracy.

As mentioned, however, there may be at least some regions that only need to be evaluated for an event if a state of a primary field or region has changed. As an example, the regions in FIG. 2B have been divided into two levels or layers of an event hierarchy 220, where each level corresponds to a different state and can be evaluated in a separate analysis pass. In this example, a game has a rule for a “kill” type of event, where a kill icon is designated as a primary region, and regions high kill and bot mode are identified as subordinate regions. These subordinate regions will only be evaluated for frames in which, or proximate which, a kill icon changes or has a determined state or value. If a kill icon does not change or have one of these values, then these subordinate regions will not be evaluated. Other regions, such as flashbang and spectator band, may be evaluated on each frame, or may not be evaluated, but may not be included in the event rule. In the hierarchy 240 of FIG. 240 , however, a rule may specify a primary region, such as kill icon, and all other regions then become a subordinate region for at least that rule, and are then checked, analyzed, or evaluated only when a kill icon reaches, changes, or represents a specific state or value. In the example hierarchy 260 of FIG. 2D, there may be additional levels in such a hierarchy, where certain fields or regions are only analyzed if at least one state, change, or value in a higher level of the hierarchy means that, according to the respective rule, that field or region should be checked, analyzed, or evaluated. In at least one embodiment, a game can have any number of fields or regions, and a rule may select any number of these regions to be included at any of a number of different levels of an event hierarchy. The rule can also specify one or more criteria for regions of a lower level to be evaluated, such as a field or region in a higher level having a specific value or state, being within or outside a specified range, changing by more than or less than a threshold amount, and so on.

It may be the case that a given game or experience has multiple modes of operation or gameplay. For example, a game may have a mode or level that operates as a first person shooter, a mode where a player operates a vehicle, a mode where a player must solve a puzzle, and so on. For each of these different modes, there may be different fields or regions displayed that may include different types of information. For each of these modes, there may also be different types of events that are to be selected for a highlight video. Accordingly, in at least one embodiment an event hierarchy might include different rules with different primary regions as illustrated in example hierarchy 280 of FIG. 2E. In such situations, there may be one or more regions that are evaluated to determine a current mode of gameplay. For that given mode, there may be one or more primary regions to be analyzed to detect types of events relevant for that mode of gameplay. In some embodiments, frames can be analyzed to attempt to determine a presence of one or more regions to assist in determining a current mode of gameplay. In at least one embodiment, determination of a game mode can also cause regions unrelated to that game mode to be filtered, or removed, from consideration. In this way, game rules, events, and regions can be mapped to a tree of text, icons, sounds, or other elements present, as may be part of a GUI or HUD.

FIGS. 3A and 3B provide an example of how such a hierarchy can be utilized in accordance with at least one embodiment. In the image 300 of FIG. 3A, a primary region 302 is illustrated that contains a graphical element of interest, in this case a player status bar that indicates the status of other players in a game. While an oval region is illustrated, it should be understood that the region can have any appropriate size and shape that bounds at least a relevant portion of an element of interest, and may have at least some buffer to allow for slight variation, where a rectangular bounding box may be used in many instances. In an example where player kills are a trigger for a highlight to be generated, the player status bar may be used as a determining trigger in a primary region. This primary region 302 can be analyzed, as part of a first or primary pass, on each frame to attempt to determine when there is a meaningful change in state. In at least one embodiment, this can include the bar changing to illustrate that a player has been eliminated or is no longer active in this current game session. There may be other states as well, such as to indicate when a player has been knocked down or has low health, and these may not satisfy the selection criterion for a highlight in this example.

When an actionable change is detected in this primary region 302, such as when an icon of the status bar changes to indicate that a player is no longer active in this session, other information for that frame 350, or at least one proximate frame, can be analyzed during at least one subsequent pass to attempt to determine whether a highlight should be generated, or other such action taken. In this example, there may be three subordinate regions at a lower level in an event hierarchy, under the status bar primary region. In this example, these include a chat region 352, a cash region 354, and an ammunition region 356. These subordinate regions can be analyzed to determine whether an event has occurred that should trigger a highlight, based on a detected change in the primary region. In this example, chat messages in the chat region 352 may be analyzed, such as by using a text analyzer, to attempt to determine whether information is provided as to the type or source of an event, such as indication of a player making a kill. A change in an amount of cash in a cash region 354 may be indicative of a kill if a player receives an amount of cash for a kill, and the cash has recently gone up by that amount. Further, an amount of ammunition in an ammunition region 356 can be analyzed to determine whether that amount recently changed to reflect ammunition being used, as an indication that no ammunition has been used recently may, in at least this game, be an indication that this player did not lead to the death of the other player. Various other types of regions or analysis can be used as well within the scope of the various embodiments. Further, there may be additional subordinate regions at lower levels of an event hierarchy for this event that may be analyzed in response to one or more of these subordinate regions 352, 354, 356 having a determined state, or change in state.

In at least one embodiment, at least some of this image or video content may be provided or presented locally on a client device 402 as illustrated in FIG. 4 . At least a portion of this content may be provided by a content server 420, such as a game server or provider system, across at least one wired or wireless network 440. In at least one embodiment, content to be presented may include various types of content, as may include video game, virtual reality (VR), augmented reality (AR), mixed reality (MR), image, textual, audio, haptic, or video content. Client device 402 may include or comprise a device such as a desktop computer, notebook computer, gaming console, smart phone, tablet computer, VR headset, AR/MR goggles, a wearable computer, or a smart television.

In some embodiments, content provided to, or generated on, client device 402 may include highlights from specific media, such as a game hosted on client device 402, content server 420, or third party content service 450. In some embodiments, media may be received to client device 402 and highlights determined using an event detector 410 and highlight generator 412 of a content application executing on client device 402. In other embodiments, an event detection module 440 and highlight generator 442 might run in a content application 424 running on content server 420, or in a highlight application 452 on a third party content service 450, where those highlights can then be transmitted to one or more other client devices 460 for display as well. As mentioned, one or more neural networks may be used for purposes such as event detection, criteria evaluation, and/or highlight selection.

In at least one embodiment, client device 402 can generate content for a session, such as a gaming session or video viewing session, using components of a content application 404 on client device 402 and data stored locally on that client device. This content may be analyzed in various embodiments for purposes such as to generate highlights or training videos. In at least one embodiment, a content application 424 (e.g., a gaming or streaming media application) executing on content server 420 can initiate a session associated with at least client device 402, as may utilize a session manager and user data stored in a user database 446, and can cause content 444 to be determined by a content manager 426 and rendered using a rendering engine 428, if needed for this type of content or platform, and transmitted to client device 402 using an appropriate transmission manager 422 to send by download, streaming, or another such transmission channel. In at least one embodiment, client device 402 receiving this content can provide this content to a corresponding content application 404, which may also or alternatively include a rendering engine 410 for rendering at least some of this content for presentation via client device 402, such as video content through a display 406 and audio, such as sounds and music, through at least one audio playback device 408, such as speakers or headphones. In at least one embodiment, at least some of this content may already be stored on, rendered on, or accessible to client device 402 such that transmission over network 440 is not required for at least that portion of content, such as where that content may have been previously downloaded or stored locally on a hard drive or optical disk. In at least one embodiment, a transmission mechanism such as data streaming can be used to transfer this content from server 420, or content database 444, to client device 402. In at least one embodiment, at least a portion of this content can be obtained or streamed from another source, such as a third party content service 450 that may also include a highlight application 452 for generating or providing content.

FIG. 5A illustrates components of an example highlight generation system 500 that can be utilized in accordance with at least one embodiment. In this example, video data 502 is received for analysis in selecting highlight clips. This video data can include a full download or transmission of data, or streaming of live data content, among other such options. In this example, the video content is provided as input to a highlight generation module 504, system, or service. The video can be passed to an event recognition module 506 that can attempt to identify specific events represented in the video. This can include, for example, analyzing content in specific regions of video and determining a state, or change in state, for one or more elements in that region. One or more neural networks may be utilized that are trained to classify different types of objects that may be represented in a video frame. As mentioned, there may hierarchical levels of regions, and an event recognition module might first analyze only content for one or more primary regions. In this example, the event recognition module 506 can analyze information in these primary regions, and can pass this information to an event analysis module 508. An event recognition module can use one or more event auto-recognition algorithms, processes, or deep learning approaches to recognize events, or objects and occurrences associated with various types of events. This event analysis module can analyze the information to determine whether the information in one or more primary region has a state, or has had a change in state, that warrants further investigation for highlight selection. If so, the event recognition module 506 can evaluate one or more subordinate regions, as may be determined by one or more rules for one or more specific types of event. Information from these subordinate regions can then be passed to the event analysis module 508 to determine whether one or more highlight selection criteria have been satisfied. For a kill event, a highlight selection criterion might include a determination that a current player killed another player with at least 85% certainty based at least in part upon the information from these regions. If such a criterion is satisfied, information for that event can be passed to a highlight generation module 510, which can be responsible for generating a corresponding highlight. This can include, for example, pulling video data from a video buffer 514, where the video may include some amount of video content before, and after, a timing of the event. In another embodiment, this may include determining timing information for this highlight to be used to pull that video content at a later time. This highlight information for one or more highlights 512 can then be provided as output, to be stored for subsequent viewing or presentation via a client device as those highlights are determined.

FIG. 5B illustrates a process 550 for determining highlights using a system such as that described with respect to FIG. 5A. It should be understood that for this and other processes presented herein that there can be additional, fewer, or alternative steps performed in similar or alternative order, or at least partially in parallel, within scope of various embodiments unless otherwise specifically stated. As mentioned previously, identifying events can be useful for other purposes as well, such as for testing or training purposes. In this example, video data is received 552 that includes content that may be useful in generating one or more highlights. There may be one or more regions of interest identified for this type of video content, including at least two different types of regions, such as primary and subordinate regions. One or more first regions of this video data can be analyzed 554 to attempt to recognize events of a first type. This may include analyzing primary regions to attempt to identify a state, or change in state, of one or more interface elements. In at least one embodiment, the second regions are not analyzed unless a first type of event is recognized in a video frame for one or the first regions. Upon recognition of an event of the first type, first or second regions of this video data can be analyzed 556, such as to identify related state information for other interface elements. It may be determined 558, based at least in part upon data from these first and second regions, that this identified event satisfies a highlight criterion. If so, relevant video data can be selected 560 from an appropriate video buffer or file. At least that portion of the video data, relevant to the determined event, can then be provided 562 for inclusion as a segment in a generated highlight video.

FIG. 6 illustrates an example process 600 for determining whether an event satisfies a selection criterion that can be performed in accordance with at least one embodiment. In this example, one or more frames of video data are analyzed 602. This can include, for example, attempting to determine one or more objects, actions, events, or occurrences that may be indicative of a game, or mode of gameplay. This data may be determined in at least one embodiment by using one or more neural networks, such as one or more convolutional neural networks (CNNs) trained to recognize different types of objects in image or video data. A mode of gameplay can then be determined 604 based at least in part upon this video data. This may include, for example, a determination as to whether rules should be utilized that relate to driving, sports, or puzzle gameplay of an identified game. Once a current mode is determined, one or more regions and event types can be determined 606 for that game mode of the current game. In at least one embodiment, a customized set of rules and regions can be provided for each game, or type of game, as well as different modes of gameplay or operation within that game. For one or more current frames of video content representative of gameplay, one or more primary regions of a region hierarchy can be analyzed 608 to attempt to address changes, or specific state(s), of elements within those regions. If it is determined 610 that no actionable change has occurred, then the process can continue with one or more subsequent frames.

If it is determined that an actionable change was detected in a primary region, then one or more subordinate regions at a next lowest level of the region hierarchy can be analyzed 612 to attempt to determine actionable changes, transitions, or specific state values. If it is determined 614 that there are more levels in this hierarchy, and such analysis is warranted based on information from regions at a current level, then the process can continue at this next lowest level. Once the relevant subordinate regions have been analyzed, it can be determined 616 whether data from those regions satisfies a selection criterion. If it is determined 618 that such a criterion has not been satisfied, then the process can continue with one or more subsequent frames. If it is determined that a selection criterion has been satisfied, then information for a portion of the video data that satisfies this selection criterion can be provided 620 for use, such as to generate a highlight or training video. This process can then continue for subsequent frames until the end of the video is reached, a maximum number of highlights has been reached, or another such end criterion is met. In some embodiments, there may be at least one subsequent step to determine, from the selected highlights, which highlights to include in a final highlight sequence or montage.

In some embodiments, event regions and region hierarchies can be determined manually. In at least one embodiment, at least some of these regions and hierarchies can be determined automatically, as may be based at least in part upon event rules for a game or other type of content. In at least one embodiment, a Bayesian approach can be used to determine which regions change along with, or in response to, changes in other regions. Based at least in part upon this data, relationships can be learned that can be used to produce hierarchies of event regions. In at least some embodiments, a user may be able to specify certain fields, rules, events, or hierarchies for generating highlights or otherwise performing tasks based at least in part upon detected events. A user may also be able to activate or deactivate highlights for different game modes or types of gameplay, such as where a user only wants to see certain types of highlights. In at least one embodiment, additional fields can be introduced to an event dictionary to indicate associations with event regions, as well as the type of region or position in an event hierarchy. Inclusion of these labels in an event dictionary can ensure that consistent terminology and labeling is utilized across different games or other types of content.

As mentioned, the determination of events using such an approach can provide additional benefit as well. For example, the ability to track player events with little additional computational overhead provides an ability to more accurately learn the behavior or playing style of a user, which can help for purposes such as player skill determination, as may be useful for matchmaking or difficulty setting, as well as training or recommendations that may be presented during a game. Learning how a player plays a game can also help to better understand which regions are likely to be indicative of certain events based on that player's style, as well as relative weightings to be given to those regions.

In at least one embodiment, an API may provide access to methods that allow users with appropriate credentials to associate models with applications, such that models may be executed as part of execution of containerized instantiations of applications.

In at least one embodiment, training pipeline 1404 (FIG. 14 ) may include a scenario where facility 1302 is training their own machine learning model, or has an existing machine learning model that needs to be optimized or updated. In at least one embodiment, imaging data 1308 generated by imaging device(s), sequencing devices, and/or other device types may be received.

In at least one embodiment, each application may perform one or more processing tasks in an advanced processing and inferencing pipeline (e.g., inferencing, object detection, feature detection, segmentation, image enhancement, calibration, etc.). In at least one embodiment, an advanced processing and inferencing pipeline may be defined based on selections of different containers that are desired or required for processing imaging data 1308, in addition to containers that receive and configure imaging data for use by each container and/or for use by facility 1302 after processing through a pipeline (e.g., to convert outputs back to a usable data type). In at least one embodiment, a combination of containers within software 1318 (e.g., that make up a pipeline) may be referred to as a virtual instrument (as described in more detail herein), and a virtual instrument may leverage services 1320 and hardware 1322 to execute some or all processing tasks of applications instantiated in containers.

In at least one embodiment, because DICOM objects may contain anywhere from one to hundreds of images or other data types, and due to a variation in data, a developer may be responsible for managing (e.g., setting constructs for, building pre-processing into an application, etc.) extraction and preparation of incoming data. In at least one embodiment, once validated by system 1400 (e.g., for accuracy), an application may be available in a container registry for selection and/or implementation by a user to perform one or more processing tasks with respect to data at a facility (e.g., a second facility) of a user.

In at least one embodiment, developers may then share applications or containers through a network for access and use by users of a system (e.g., system 1400 of FIG. 14 ).

In at least one embodiment, training system 1304 may execute training pipelines 1404, similar to those described herein with respect to FIG. 13 . In at least one embodiment, where one or more machine learning models are to be used in deployment pipelines 1410 by deployment system 1306, training pipelines 1404 may be used to train or retrain one or more (e.g. pre-trained) models, and/or implement one or more of pre-trained models 1406 (e.g., without a need for retraining or updating).

In at least one embodiment, ground truth data may be synthetically produced (e.g., generated from computer models or renderings), real produced (e.g., designed and produced from real-world data), machine-automated (e.g., using feature analysis and learning to extract features from data and then generate labels), human annotated (e.g., labeler, or annotation expert, defines location of labels), and/or a combination thereof. In at least one embodiment, for each instance of imaging data 1308 (or other data type used by machine learning models), there may be corresponding ground truth data generated by training system 1304. In at least one embodiment, AI-assisted annotation may be performed as part of deployment pipelines 1410; either in addition to, or in lieu of AI-assisted annotation included in training pipelines 1404. In at least one embodiment, system 1400 may include a multi-layer platform that may include a software layer (e.g., software 1318) of diagnostic applications (or other application types) that may perform one or more medical imaging and diagnostic functions. In at least one embodiment, system 1400 may be communicatively coupled to (e.g., via encrypted links) PACS server networks of one or more facilities. In at least one embodiment, system 1400 may be configured to access and referenced data from PACS servers to perform operations, such as training machine learning models, deploying machine learning models, image processing, inferencing, and/or other operations.

In at least one embodiment, a software layer may be implemented as a secure, encrypted, and/or authenticated API through which applications or containers may be invoked (e.g., called) from an external environment(s) (e.g., facility 1302). In at least one embodiment, applications may then call or execute one or more services 1320 for performing compute, AI, or visualization tasks associated with respective applications, and software 1318 and/or services 1320 may leverage hardware 1322 to perform processing tasks in an effective and efficient manner.

In at least one embodiment, deployment system 1306 may execute deployment pipelines 1410. In at least one embodiment, deployment pipelines 1410 may include any number of applications that may be sequentially, non-sequentially, or otherwise applied to imaging data (and/or other data types) generated by imaging devices, sequencing devices, genomics devices, etc. —including AI-assisted annotation, as described above. In at least one embodiment, as described herein, a deployment pipeline 1410 for an individual device may be referred to as a virtual instrument for a device (e.g., a virtual ultrasound instrument, a virtual CT scan instrument, a virtual sequencing instrument, etc.). In at least one embodiment, for a single device, there may be more than one deployment pipeline 1410 depending on information desired from data generated by a device. In at least one embodiment, where detections of anomalies are desired from an Mill machine, there may be a first deployment pipeline 1410, and where image enhancement is desired from output of an Mill machine, there may be a second deployment pipeline 1410.

In at least one embodiment, an image generation application may include a processing task that includes use of a machine learning model. In at least one embodiment, a user may desire to use their own machine learning model, or to select a machine learning model from model registry 1324. In at least one embodiment, a user may implement their own machine learning model or select a machine learning model for inclusion in an application for performing a processing task. In at least one embodiment, applications may be selectable and customizable, and by defining constructs of applications, deployment and implementation of applications for a particular user are presented as a more seamless user experience. In at least one embodiment, by leveraging other features of system 1400— such as services 1320 and hardware 1322— deployment pipelines 1410 may be even more user friendly, provide for easier integration, and produce more accurate, efficient, and timely results.

In at least one embodiment, deployment system 1306 may include a user interface 1414 (e.g., a graphical user interface, a web interface, etc.) that may be used to select applications for inclusion in deployment pipeline(s) 1410, arrange applications, modify or change applications or parameters or constructs thereof, use and interact with deployment pipeline(s) 1410 during set-up and/or deployment, and/or to otherwise interact with deployment system 1306. In at least one embodiment, although not illustrated with respect to training system 1304, user interface 1414 (or a different user interface) may be used for selecting models for use in deployment system 1306, for selecting models for training, or retraining, in training system 1304, and/or for otherwise interacting with training system 1304.

In at least one embodiment, pipeline manager 1412 may be used, in addition to an application orchestration system 1428, to manage interaction between applications or containers of deployment pipeline(s) 1410 and services 1320 and/or hardware 1322. In at least one embodiment, pipeline manager 1412 may be configured to facilitate interactions from application to application, from application to service 1320, and/or from application or service to hardware 1322. In at least one embodiment, although illustrated as included in software 1318, this is not intended to be limiting, and in some examples (e.g., as illustrated in FIG. 12 cc) pipeline manager 1412 may be included in services 1320. In at least one embodiment, application orchestration system 1428 (e.g., Kubernetes, DOCKER, etc.) may include a container orchestration system that may group applications into containers as logical units for coordination, management, scaling, and deployment. In at least one embodiment, by associating applications from deployment pipeline(s) 1410 (e.g., a reconstruction application, a segmentation application, etc.) with individual containers, each application may execute in a self-contained environment (e.g., at a kernel level) to increase speed and efficiency.

In at least one embodiment, each application and/or container (or image thereof) may be individually developed, modified, and deployed (e.g., a first user or developer may develop, modify, and deploy a first application and a second user or developer may develop, modify, and deploy a second application separate from a first user or developer), which may allow for focus on, and attention to, a task of a single application and/or container(s) without being hindered by tasks of another application(s) or container(s). In at least one embodiment, communication, and cooperation between different containers or applications may be aided by pipeline manager 1412 and application orchestration system 1428. In at least one embodiment, so long as an expected input and/or output of each container or application is known by a system (e.g., based on constructs of applications or containers), application orchestration system 1428 and/or pipeline manager 1412 may facilitate communication among and between, and sharing of resources among and between, each of applications or containers. In at least one embodiment, because one or more of applications or containers in deployment pipeline(s) 1410 may share same services and resources, application orchestration system 1428 may orchestrate, load balance, and determine sharing of services or resources between and among various applications or containers. In at least one embodiment, a scheduler may be used to track resource requirements of applications or containers, current usage or planned usage of these resources, and resource availability. In at least one embodiment, a scheduler may thus allocate resources to different applications and distribute resources between and among applications in view of requirements and availability of a system. In some examples, a scheduler (and/or other component of application orchestration system 1428) may determine resource availability and distribution based on constraints imposed on a system (e.g., user constraints), such as quality of service (QoS), urgency of need for data outputs (e.g., to determine whether to execute real-time processing or delayed processing), etc.

In at least one embodiment, services 1320 leveraged by and shared by applications or containers in deployment system 1306 may include compute services 1416, AI services 1418, visualization services 1420, and/or other service types. In at least one embodiment, applications may call (e.g., execute) one or more of services 1320 to perform processing operations for an application. In at least one embodiment, compute services 1416 may be leveraged by applications to perform super-computing or other high-performance computing (HPC) tasks. In at least one embodiment, compute service(s) 1416 may be leveraged to perform parallel processing (e.g., using a parallel computing platform 1430) for processing data through one or more of applications and/or one or more tasks of a single application, substantially simultaneously. In at least one embodiment, parallel computing platform 1430 (e.g., NVIDIA's CUDA) may enable general purpose computing on GPUs (GPGPU) (e.g., GPUs 1422). In at least one embodiment, a software layer of parallel computing platform 1430 may provide access to virtual instruction sets and parallel computational elements of GPUs, for execution of compute kernels. In at least one embodiment, parallel computing platform 1430 may include memory and, in some embodiments, a memory may be shared between and among multiple containers, and/or between and among different processing tasks within a single container. In at least one embodiment, inter-process communication (IPC) calls may be generated for multiple containers and/or for multiple processes within a container to use same data from a shared segment of memory of parallel computing platform 1430 (e.g., where multiple different stages of an application or multiple applications are processing same information). In at least one embodiment, rather than making a copy of data and moving data to different locations in memory (e.g., a read/write operation), same data in same location of a memory may be used for any number of processing tasks (e.g., at a same time, at different times, etc.). In at least one embodiment, as data is used to generate new data as a result of processing, this information of a new location of data may be stored and shared between various applications. In at least one embodiment, location of data and a location of updated or modified data may be part of a definition of how a payload is understood within containers.

In at least one embodiment, AI services 1418 may be leveraged to perform inferencing services for executing machine learning model(s) associated with applications (e.g., tasked with performing one or more processing tasks of an application). In at least one embodiment, AI services 1418 may leverage AI system 1424 to execute machine learning model(s) (e.g., neural networks, such as CNNs) for segmentation, reconstruction, object detection, feature detection, classification, and/or other inferencing tasks. In at least one embodiment, applications of deployment pipeline(s) 1410 may use one or more of output models 1316 from training system 1304 and/or other models of applications to perform inference on imaging data. In at least one embodiment, two or more examples of inferencing using application orchestration system 1428 (e.g., a scheduler) may be available. In at least one embodiment, a first category may include a high priority/low latency path that may achieve higher service level agreements, such as for performing inference on urgent requests during an emergency, or for a radiologist during diagnosis. In at least one embodiment, a second category may include a standard priority path that may be used for requests that may be non-urgent or where analysis may be performed at a later time. In at least one embodiment, application orchestration system 1428 may distribute resources (e.g., services 1320 and/or hardware 1322) based on priority paths for different inferencing tasks of AI services 1418.

In at least one embodiment, shared storage may be mounted to AI services 1418 within system 1400. In at least one embodiment, shared storage may operate as a cache (or other storage device type) and may be used to process inference requests from applications. In at least one embodiment, when an inference request is submitted, a request may be received by a set of API instances of deployment system 1306, and one or more instances may be selected (e.g., for best fit, for load balancing, etc.) to process a request. In at least one embodiment, to process a request, a request may be entered into a database, a machine learning model may be located from model registry 1324 if not already in a cache, a validation step may ensure appropriate machine learning model is loaded into a cache (e.g., shared storage), and/or a copy of a model may be saved to a cache. In at least one embodiment, a scheduler (e.g., of pipeline manager 1412) may be used to launch an application that is referenced in a request if an application is not already running or if there are not enough instances of an application. In at least one embodiment, if an inference server is not already launched to execute a model, an inference server may be launched. Any number of inference servers may be launched per model. In at least one embodiment, in a pull model, in which inference servers are clustered, models may be cached whenever load balancing is advantageous. In at least one embodiment, inference servers may be statically loaded in corresponding, distributed servers.

In at least one embodiment, inferencing may be performed using an inference server that runs in a container. In at least one embodiment, an instance of an inference server may be associated with a model (and optionally a plurality of versions of a model). In at least one embodiment, if an instance of an inference server does not exist when a request to perform inference on a model is received, a new instance may be loaded. In at least one embodiment, when starting an inference server, a model may be passed to an inference server such that a same container may be used to serve different models so long as inference server is running as a different instance.

In at least one embodiment, during application execution, an inference request for a given application may be received, and a container (e.g., hosting an instance of an inference server) may be loaded (if not already), and a start procedure may be called. In at least one embodiment, pre-processing logic in a container may load, decode, and/or perform any additional pre-processing on incoming data (e.g., using a CPU(s) and/or GPU(s)). In at least one embodiment, once data is prepared for inference, a container may perform inference as necessary on data. In at least one embodiment, this may include a single inference call on one image (e.g., a hand X-ray), or may require inference on hundreds of images (e.g., a chest CT). In at least one embodiment, an application may summarize results before completing, which may include, without limitation, a single confidence score, pixel level-segmentation, voxel-level segmentation, generating a visualization, or generating text to summarize findings. In at least one embodiment, different models or applications may be assigned different priorities. For example, some models may have a real-time (TAT<1 min) priority while others may have lower priority (e.g., TAT<10 min). In at least one embodiment, model execution times may be measured from requesting institution or entity and may include partner network traversal time, as well as execution on an inference service.

In at least one embodiment, transfer of requests between services 1320 and inference applications may be hidden behind a software development kit (SDK), and robust transport may be provide through a queue. In at least one embodiment, a request will be placed in a queue via an API for an individual application/tenant ID combination and an SDK will pull a request from a queue and give a request to an application. In at least one embodiment, a name of a queue may be provided in an environment from where an SDK will pick it up. In at least one embodiment, asynchronous communication through a queue may be useful as it may allow any instance of an application to pick up work as it becomes available. Results may be transferred back through a queue, to ensure no data is lost. In at least one embodiment, queues may also provide an ability to segment work, as highest priority work may go to a queue with most instances of an application connected to it, while lowest priority work may go to a queue with a single instance connected to it that processes tasks in an order received. In at least one embodiment, an application may run on a GPU-accelerated instance generated in cloud 1426, and an inference service may perform inferencing on a GPU.

In at least one embodiment, visualization services 1420 may be leveraged to generate visualizations for viewing outputs of applications and/or deployment pipeline(s) 1410. In at least one embodiment, GPUs 1422 may be leveraged by visualization services 1420 to generate visualizations. In at least one embodiment, rendering effects, such as ray-tracing, may be implemented by visualization services 1420 to generate higher quality visualizations. In at least one embodiment, visualizations may include, without limitation, 2D image renderings, 3D volume renderings, 3D volume reconstruction, 2D tomographic slices, virtual reality displays, augmented reality displays, etc. In at least one embodiment, virtualized environments may be used to generate a virtual interactive display or environment (e.g., a virtual environment) for interaction by users of a system (e.g., doctors, nurses, radiologists, etc.). In at least one embodiment, visualization services 1420 may include an internal visualizer, cinematics, and/or other rendering or image processing capabilities or functionality (e.g., ray tracing, rasterization, internal optics, etc.).

In at least one embodiment, hardware 1322 may include GPUs 1422, AI system 1424, cloud 1426, and/or any other hardware used for executing training system 1304 and/or deployment system 1306. In at least one embodiment, GPUs 1422 (e.g., NVIDIA's TESLA and/or QUADRO GPUs) may include any number of GPUs that may be used for executing processing tasks of compute services 1416, AI services 1418, visualization services 1420, other services, and/or any of features or functionality of software 1318. For example, with respect to AI services 1418, GPUs 1422 may be used to perform pre-processing on imaging data (or other data types used by machine learning models), post-processing on outputs of machine learning models, and/or to perform inferencing (e.g., to execute machine learning models). In at least one embodiment, cloud 1426, AI system 1424, and/or other components of system 1400 may use GPUs 1422. In at least one embodiment, cloud 1426 may include a GPU-optimized platform for deep learning tasks. In at least one embodiment, AI system 1424 may use GPUs, and cloud 1426— or at least a portion tasked with deep learning or inferencing—may be executed using one or more AI systems 1424. As such, although hardware 1322 is illustrated as discrete components, this is not intended to be limiting, and any components of hardware 1322 may be combined with, or leveraged by, any other components of hardware 1322.

In at least one embodiment, AI system 1424 may include a purpose-built computing system (e.g., a super-computer or an HPC) configured for inferencing, deep learning, machine learning, and/or other artificial intelligence tasks. In at least one embodiment, AI system 1424 (e.g., NVIDIA's DGX) may include GPU-optimized software (e.g., a software stack) that may be executed using a plurality of GPUs 1422, in addition to CPUs, RAM, storage, and/or other components, features, or functionality. In at least one embodiment, one or more AI systems 1424 may be implemented in cloud 1426 (e.g., in a data center) for performing some or all of AI-based processing tasks of system 1400.

In at least one embodiment, cloud 1426 may include a GPU-accelerated infrastructure (e.g., NVIDIA's NGC) that may provide a GPU-optimized platform for executing processing tasks of system 1400. In at least one embodiment, cloud 1426 may include an AI system(s) 1424 for performing one or more of AI-based tasks of system 1400 (e.g., as a hardware abstraction and scaling platform). In at least one embodiment, cloud 1426 may integrate with application orchestration system 1428 leveraging multiple GPUs to enable seamless scaling and load balancing between and among applications and services 1320. In at least one embodiment, cloud 1426 may tasked with executing at least some of services 1320 of system 1400, including compute services 1416, AI services 1418, and/or visualization services 1420, as described herein.

FIG. 15A illustrates a data flow diagram for a process 1500 to train, retrain, or update a machine learning model, in accordance with at least one embodiment. In at least one embodiment, process 1500 may be executed using, as a non-limiting example, system 1400 of FIG. 14 . In at least one embodiment, process 1500 may leverage services 1320 and/or hardware 1322 of system 1400, as described herein. In at least one embodiment, refined models 1512 generated by process 1500 may be executed by deployment system 1306 for one or more containerized applications in deployment pipelines 1410.

In at least one embodiment, model training 1314 may include retraining or updating an initial model 1504 (e.g., a pre-trained model) using new training data (e.g., new input data, such as customer dataset 1506, and/or new ground truth data associated with input data). In at least one embodiment, to retrain, or update, initial model 1504, output or loss layer(s) of initial model 1504 may be reset, or deleted, and/or replaced with an updated or new output or loss layer(s). In at least one embodiment, initial model 1504 may have previously fine-tuned parameters (e.g., weights and/or biases) that remain from prior training, so training or retraining 1314 may not take as long or require as much processing as training a model from scratch. In at least one embodiment, during model training 1314, by having reset or replaced output or loss layer(s) of initial model 1504, parameters may be updated and re-tuned for a new data set based on loss calculations associated with accuracy of output or loss layer(s) at generating predictions on new, customer dataset 1506 (e.g., image data 1308 of FIG. 13 ).

In at least one embodiment, pre-trained models 1406 may be stored in a data store, or registry (e.g., model registry 1324 of FIG. 13 ). In at least one embodiment, pre-trained models 1406 may have been trained, at least in part, at one or more facilities other than a facility executing process 1500. In at least one embodiment, to protect privacy and rights of patients, subjects, or clients of different facilities, pre-trained models 1406 may have been trained, on-premise, using customer or patient data generated on-premise. In at least one embodiment, pre-trained models 1406 may be trained using cloud 1426 and/or other hardware 1322, but confidential, privacy protected patient data may not be transferred to, used by, or accessible to any components of cloud 1426 (or other off premise hardware). In at least one embodiment, where a pre-trained model 1406 is trained at using patient data from more than one facility, pre-trained model 1406 may have been individually trained for each facility prior to being trained on patient or customer data from another facility. In at least one embodiment, such as where a customer or patient data has been released of privacy concerns (e.g., by waiver, for experimental use, etc.), or where a customer or patient data is included in a public data set, a customer or patient data from any number of facilities may be used to train pre-trained model 1406 on-premise and/or off premise, such as in a datacenter or other cloud computing infrastructure.

In at least one embodiment, when selecting applications for use in deployment pipelines 1410, a user may also select machine learning models to be used for specific applications. In at least one embodiment, a user may not have a model for use, so a user may select a pre-trained model 1406 to use with an application. In at least one embodiment, pre-trained model 1406 may not be optimized for generating accurate results on customer dataset 1506 of a facility of a user (e.g., based on patient diversity, demographics, types of medical imaging devices used, etc.). In at least one embodiment, prior to deploying pre-trained model 1406 into deployment pipeline 1410 for use with an application(s), pre-trained model 1406 may be updated, retrained, and/or fine-tuned for use at a respective facility.

In at least one embodiment, a user may select pre-trained model 1406 that is to be updated, retrained, and/or fine-tuned, and pre-trained model 1406 may be referred to as initial model 1504 for training system 1304 within process 1500. In at least one embodiment, customer dataset 1506 (e.g., imaging data, genomics data, sequencing data, or other data types generated by devices at a facility) may be used to perform model training 1314 (which may include, without limitation, transfer learning) on initial model 1504 to generate refined model 1512. In at least one embodiment, ground truth data corresponding to customer dataset 1506 may be generated by training system 1304. In at least one embodiment, ground truth data may be generated, at least in part, by clinicians, scientists, doctors, practitioners, at a facility (e.g., as labeled clinic data 1312 of FIG. 13 ).

In at least one embodiment, AI-assisted annotation 1310 may be used in some examples to generate ground truth data. In at least one embodiment, AI-assisted annotation 1310 (e.g., implemented using an AI-assisted annotation SDK) may leverage machine learning models (e.g., neural networks) to generate suggested or predicted ground truth data for a customer dataset. In at least one embodiment, user 1510 may use annotation tools within a user interface (a graphical user interface (GUI)) on computing device 1508.

In at least one embodiment, user 1510 may interact with a GUI via computing device 1508 to edit or fine-tune (auto)annotations. In at least one embodiment, a polygon editing feature may be used to move vertices of a polygon to more accurate or fine-tuned locations.

In at least one embodiment, once customer dataset 1506 has associated ground truth data, ground truth data (e.g., from AI-assisted annotation, manual labeling, etc.) may be used by during model training 1314 to generate refined model 1512. In at least one embodiment, customer dataset 1506 may be applied to initial model 1504 any number of times, and ground truth data may be used to update parameters of initial model 1504 until an acceptable level of accuracy is attained for refined model 1512. In at least one embodiment, once refined model 1512 is generated, refined model 1512 may be deployed within one or more deployment pipelines 1410 at a facility for performing one or more processing tasks with respect to medical imaging data.

In at least one embodiment, refined model 1512 may be uploaded to pre-trained models 1406 in model registry 1324 to be selected by another facility. In at least one embodiment, his process may be completed at any number of facilities such that refined model 1512 may be further refined on new datasets any number of times to generate a more universal model.

FIG. 15B is an example illustration of a client-server architecture 1532 to enhance annotation tools with pre-trained annotation models, in accordance with at least one embodiment. In at least one embodiment, AI-assisted annotation tools 1536 may be instantiated based on a client-server architecture 1532. In at least one embodiment, annotation tools 1536 in imaging applications may aid radiologists, for example, identify organs and abnormalities. In at least one embodiment, imaging applications may include software tools that help user 1510 to identify, as a non-limiting example, a few extreme points on a particular organ of interest in raw images 1534 (e.g., in a 3D MRI or CT scan) and receive auto-annotated results for all 2D slices of a particular organ. In at least one embodiment, results may be stored in a data store as training data 1538 and used as (for example and without limitation) ground truth data for training. In at least one embodiment, when computing device 1508 sends extreme points for AI-assisted annotation 1310, a deep learning model, for example, may receive this data as input and return inference results of a segmented organ or abnormality. In at least one embodiment, pre-instantiated annotation tools, such as AI-Assisted Annotation Tool 1536B in FIG. 15B, may be enhanced by making API calls (e.g., API Call 1544) to a server, such as an Annotation Assistant Server 1540 that may include a set of pre-trained models 1542 stored in an annotation model registry, for example. In at least one embodiment, an annotation model registry may store pre-trained models 1542 (e.g., machine learning models, such as deep learning models) that are pre-trained to perform AI-assisted annotation on a particular organ or abnormality. These models may be further updated by using training pipelines 1404. In at least one embodiment, pre-installed annotation tools may be improved over time as new labeled clinic data 1312 is added.

Such components can be used to analyze specific regions of content in order to determine an occurrence of an event of interest without having to analyze all such regions. These events can be used for various purposes, such as to generate highlight sequences.

Other variations are within spirit of present disclosure. Thus, while disclosed techniques are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in drawings and have been described above in detail. It should be understood, however, that there is no intention to limit disclosure to specific form or forms disclosed, but on contrary, intention is to cover all modifications, alternative constructions, and equivalents falling within spirit and scope of disclosure, as defined in appended claims.

Use of terms “a” and “an” and “the” and similar referents in context of describing disclosed embodiments (especially in context of following claims) are to be construed to cover both singular and plural, unless otherwise indicated herein or clearly contradicted by context, and not as a definition of a term. Terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (meaning “including, but not limited to,”) unless otherwise noted. Term “connected,” when unmodified and referring to physical connections, is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within range, unless otherwise indicated herein and each separate value is incorporated into specification as if it were individually recited herein. Use of term “set” (e.g., “a set of items”) or “subset,” unless otherwise noted or contradicted by context, is to be construed as a nonempty collection comprising one or more members. Further, unless otherwise noted or contradicted by context, term “subset” of a corresponding set does not necessarily denote a proper subset of corresponding set, but subset and corresponding set may be equal.

Conjunctive language, such as phrases of form “at least one of A, B, and C,” or “at least one of A, B and C,” unless specifically stated otherwise or otherwise clearly contradicted by context, is otherwise understood with context as used in general to present that an item, term, etc., may be either A or B or C, or any nonempty subset of set of A and B and C. For instance, in illustrative example of a set having three members, conjunctive phrases “at least one of A, B, and C” and “at least one of A, B and C” refer to any of following sets: {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, {A, B, C}. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of A, at least one of B, and at least one of C each to be present. In addition, unless otherwise noted or contradicted by context, term “plurality” indicates a state of being plural (e.g., “a plurality of items” indicates multiple items). A plurality is at least two items, but can be more when so indicated either explicitly or by context. Further, unless stated otherwise or otherwise clear from context, phrase “based on” means “based at least in part on” and not “based solely on.”

Operations of processes described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. In at least one embodiment, a process such as those processes described herein (or variations and/or combinations thereof) is performed under control of one or more computer systems configured with executable instructions and is implemented as code (e.g., executable instructions, one or more computer programs or one or more applications) executing collectively on one or more processors, by hardware or combinations thereof. In at least one embodiment, code is stored on a computer-readable storage medium, for example, in form of a computer program comprising a plurality of instructions executable by one or more processors. In at least one embodiment, a computer-readable storage medium is a non-transitory computer-readable storage medium that excludes transitory signals (e.g., a propagating transient electric or electromagnetic transmission) but includes non-transitory data storage circuitry (e.g., buffers, cache, and queues) within transceivers of transitory signals. In at least one embodiment, code (e.g., executable code or source code) is stored on a set of one or more non-transitory computer-readable storage media having stored thereon executable instructions (or other memory to store executable instructions) that, when executed (i.e., as a result of being executed) by one or more processors of a computer system, cause computer system to perform operations described herein. A set of non-transitory computer-readable storage media, in at least one embodiment, comprises multiple non-transitory computer-readable storage media and one or more of individual non-transitory storage media of multiple non-transitory computer-readable storage media lack all of code while multiple non-transitory computer-readable storage media collectively store all of code. In at least one embodiment, executable instructions are executed such that different instructions are executed by different processors—for example, a non-transitory computer-readable storage medium store instructions and a main central processing unit (“CPU”) executes some of instructions while a graphics processing unit (“GPU”) executes other instructions. In at least one embodiment, different components of a computer system have separate processors and different processors execute different subsets of instructions.

Accordingly, in at least one embodiment, computer systems are configured to implement one or more services that singly or collectively perform operations of processes described herein and such computer systems are configured with applicable hardware and/or software that enable performance of operations. Further, a computer system that implements at least one embodiment of present disclosure is a single device and, in another embodiment, is a distributed computer system comprising multiple devices that operate differently such that distributed computer system performs operations described herein and such that a single device does not perform all operations.

Use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate embodiments of disclosure and does not pose a limitation on scope of disclosure unless otherwise claimed. No language in specification should be construed as indicating any non-claimed element as essential to practice of disclosure.

All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.

In description and claims, terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms may be not intended as synonyms for each other. Rather, in particular examples, “connected” or “coupled” may be used to indicate that two or more elements are in direct or indirect physical or electrical contact with each other. “Coupled” may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.

Unless specifically stated otherwise, it may be appreciated that throughout specification terms such as “processing,” “computing,” “calculating,” “determining,” or like, refer to action and/or processes of a computer or computing system, or similar electronic computing device, that manipulate and/or transform data represented as physical, such as electronic, quantities within computing system's registers and/or memories into other data similarly represented as physical quantities within computing system's memories, registers or other such information storage, transmission or display devices.

In a similar manner, term “processor” may refer to any device or portion of a device that processes electronic data from registers and/or memory and transform that electronic data into other electronic data that may be stored in registers and/or memory. As non-limiting examples, “processor” may be a CPU or a GPU. A “computing platform” may comprise one or more processors. As used herein, “software” processes may include, for example, software and/or hardware entities that perform work over time, such as tasks, threads, and intelligent agents. Also, each process may refer to multiple processes, for carrying out instructions in sequence or in parallel, continuously or intermittently. Terms “system” and “method” are used herein interchangeably insofar as system may embody one or more methods and methods may be considered a system.

In present document, references may be made to obtaining, acquiring, receiving, or inputting analog or digital data into a subsystem, computer system, or computer-implemented machine. Obtaining, acquiring, receiving, or inputting analog and digital data can be accomplished in a variety of ways such as by receiving data as a parameter of a function call or a call to an application programming interface. In some implementations, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a serial or parallel interface. In another implementation, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a computer network from providing entity to acquiring entity. References may also be made to providing, outputting, transmitting, sending, or presenting analog or digital data. In various examples, process of providing, outputting, transmitting, sending, or presenting analog or digital data can be accomplished by transferring data as an input or output parameter of a function call, a parameter of an application programming interface or interprocess communication mechanism.

Although discussion above sets forth example implementations of described techniques, other architectures may be used to implement described functionality, and are intended to be within scope of this disclosure. Furthermore, although specific distributions of responsibilities are defined above for purposes of discussion, various functions and responsibilities might be distributed and divided in different ways, depending on circumstances.

Furthermore, although subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that subject matter claimed in appended claims is not necessarily limited to specific features or acts described. Rather, specific features and acts are disclosed as exemplary forms of implementing the claims.
